Easy to see. At x120 (no filter) it is an even, round glow. At x260 it appears slightly elongated NS but still no structure. The N boundary is abruptly darker while the S boundary is less well defined. With the Deep Sky filter, mottling in the disk becomes visible, but nothing suggestive of the galaxy’s name “Bear Paw”.  A foreground star visible in photos on the N edge was not seen. However the faintest of the five stars in the drawing was seen only with AV and is in Megastar as GSC3408:714, mag 15.4. Just E of it is NGC 2537A mag 15.3 glimpsed with AV.
